Re : Lasiosphaeria hirsuta ???
Hola Rafael
this looks OK - where did the blue colour come from? Something to look for in Lasiosphaeris hirsuta as it is now generally called is the formation, on some mature spores, of phialides which bud off tiny conidia, as here:

best wishes
Chris

Hi Rafael,


Ever thought about Cercophora. The spores are still no head but (can take a long time before it develops) in the ascus is a ball (Globulum). I now know not whether this also occurs in the genus Lasiosphaeria.


Peter

Re : Lasiosphaeria hirsuta ???
The subapical globose body seen in the asci of Rafael's fungus does occur in Lasiophaeris hirsuta - see: http://www.micobotanicajaen.com/Revista/Articulos/MARibesR/PirineoAragones001/Lasiosphaeris%20hirsuta%20111009%2037.pdf (particularly page 3)

Hola Peter.
no habia pensado en Cercophora, la forma macro y micro me apuntaban a lasiosphaeria, como comento dejare madurar unos dias la muestra y repetire la micro.
Un saludo
